MAX652 5V/3.3V/3V or Adjustable / High-Efficiency /

The MAX649/MAX651/MAX652 BiCMOS, step-down DCDC switching controllers provide high efficiency over three decades of load current. A unique, current-limited pulse-frequency-modulated (PFM) control scheme gives these devices the benefits of pulse-width-modulation (PWM) converters (high efficiency at h.
